The concept of "freedom" includes doing things other people think are dumb as long as others aren't harmed, as opposed to your apparent version which allows people to do only things that you personally approve of.
That's your wrong-headed concept of "freedom", which you're hoping the citizens of the USA will accept. I, on the other hand, hope they don't.
Pot's legal in Belgium. Big deal. Who wants to march in lock-step to societal meltdown with the stoned masses of Belgium? If the decision to legalize drugs was unanimous and I bet it wasn't, that's still only 10 million misguided souls.
Get real.
